SD card not being read by the system.

[a_username_that_is_cool]

My Wii U does not seem to recognize my SD card. However, my PC is fine with it.
It's modded with EnvLoader (Tiramisu/Aroma)
It does not boot into the mods though

FAT32 formatted SD card??

the SD is not a counterfeit??

the little lock on the side of the SD is not blocked from writing when inserted into the Wii U??
